But with all the options available, how will you know which are the best thermal scope? There’s a variety of price points, ranging as high as $5000, to as low as $250.

Review of Leupold 172830 LTO tracker thermal monocular

Alternate universes live just outside the wavelengths of light we can see with our eyes. Doctors use X-rays, astronomers use radio waves, and the more prepared folks can use infrared. IR, or infrared, comes in two flavors, reflected and emitted.

Gen 1 night vision uses reflected infrared light to supplement any ambient light. By using an IR emitter or IR flashlight, a scene can be lit up when viewed with night vision optics, yet remain completely dark and invisible to the naked eye.

Thermal, on the other hand, uses a special camera to view the heat signature of objects, people, and animals. Those new to Thermal Optics or TO, are in for a surprise.

Thermal imaging is like magic when needing to see inside, through, or across the wide open. And now Leupold has put a durable, versatile, and powerful thermal imager onto the market and into the hands of hunters, preparers, and anyone who wants or needs visual superpowers.

Leupold LTO?

The Leupold LTO offers a six viewing choices, and a 1x-6x zoom. The LTO runs for 10 hours on a single CR123 battery, and is built like a tank. At a hair over five and a half inches, and a dense 10 ounces, the LTO (presumably Leupold Thermal Optic) is precision machined out of aluminium and has that rock solid Leupold scope feel.

The uses for the Leupold LTO are infinite, and range from those anticipated and necessary tasks such as tracking injured game, or peering through brush for critters or people. The Leupold LTO can see beyond and through brush that blocks normal vision, and it makes no difference if it’s full daylight or the pitch blackness of night.

Instead of a photograph, a thermal camera creates a thermogram by focusing the emitted infrared light of objects in the field of view, and then digitally processes them.

The end result is an image you can see on a monitor or display that converted the invisible temperature differences in the scene into a set of shapes and colors that we can see and understand. The set of options in the Leupold LTO’s color pallet provide various ways to interpret the heat signatures of objects. Some pallets work better than others with specific subjects.

User friendly?

In the field, the Leupold LTO is nothing short of amazing. The Leupold LTO is simple to use. Hold down the on-button for a few seconds and the Leupold LTO springs to life. The LTO remembers its last thermal color setting, and fires up at 1x.

The Leupold LTO can zoom to a higher digital magnification either by steps when clicking the zoom button, or holding the zoom button down and zipping up in magnification level at tiny increments from one to six then dropping back to one again in an infinite circle.

An odd feature that asks more questions than it answers is that when the on/off buttons is toggled, a set of crosshairs appears. Since the Leupold LTO is not recommended for mounting on a rifle even though it’s an obvious one-inch tube that would have not trouble mating with conventional optics mounts. The crosshairs are a helpful addition if you have the Leupold LTO in a tripod mount, or other fixed container, but unlike the FLIR Thermal Optic Cameras, placing the crosshairs on a target does not provide any specific imaging info. Quite similar to the ATN Thor HD 384 Smart Thermal Riflescope.

The Leupold LTO has six different viewing modes or color palettes as Leupold calls them: Red, Green, White-hot, Black-hot, Black-highlight, and White-highlight. Its field of view is about 21 degrees and it has a 6x continuous digital zoom. There is no focus on the Leupold LTO, nor is there a need for one.

Controls are dirt-simple: Three buttons sit atop the unit (while it’s hard to describe a “top” for a round object, the viewing screen does have a “bottom” of sorts, so that’s what we’re using as basis): Looking through the eyepiece, the left-most button controls the color palette, while the center button controls the digital zoom and the right button toggles on/off. The LTO takes approximately 3 seconds to power up, and is designed to power down after 15 minutes of inactivity, useful when you forget to hold the power button in and it sits on your desk dutifully reading the temperature of the laminate.


  • It is water resistant and very durable.

  • It produces very excellent images.

  • It is easy to use

  • The device features easy to use controls


  • It is a bit expensive


In Conclusion

For now, the Leupold LTO Tracker remains a dedicated, hand-held thermal device. It’s excellent for hunters looking to spot an animal’s heat signature at night, or for a home defender to locate things that go bump in the night.

The price may appear steep for initial entry into thermal-imaging optics, but compared with the going rate for such devices even in the past couple of years, it’s a sea change in availability.
